Desrochers 4. PLM TOLERANCE SYNTHESIS PROCEDURE As mentioned in the preceding section, one last important link in the proposed architecture is the one which establishes the relation between design requirements in operation and design requirements at the production phase. The proposed approach to address this issue is shown in figure 3 as a “PLM tolerance synthesis procedure”. 4.1. Description of the proposed methodology The method us...
